The adjustable seat post damper really makes a difference for old bones. I'm 67 years old and still ride hard and long, but this bike makes all that SO much easier. The shock absorbing qualities of this bike are quite noticeable over my old Domane 4.7, which I dearly loved. The components are the same, but this bike is lighter and faster. I'll ride this bike in comfort for several more years (I hope!). While this bike is pretty darned expensive, you do get what you pay for. All in all, I am very satisfied with the purchase.
